BOW FOR STRINGED MUSICAL INSTRUMENTS.

SPECIFICATION forming part of Letters Patent No. 466,146, dated December29, 1891.

Application filed June 16, 1891. Serial No. 396,485 (No model.)

To all whom it may concern:

Be it known that we, WILLIAM H. AYRES and HENRY SoHRoEDEE, bothofWhipple Barracks, in the county of Yavapai and Territory of Arizona,have invented a new and Improved Bow for Stringed Musical Instruments,of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved bow forstringed musical instruments, such as violins, Violas, Violoncellos,bass viols, &c., and which is simple and durable in construction andpermits of readily, conveniently, and securely fastening the ends of thehair in the frog.

The invention consists of a frog providedwith a recess adapted toreceive the ends of the hair and awedge-shaped block fitting into thesaid recess and adapted to press or look the hair in place on one of thewalls of the recess.

The invention also consists of certain parts and details andcombinations of the same, as will be hereinafter fully described, andthen pointed out in the claims.

Reference is to be had to theaccompanyin g drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of theimprovement. Fig. 2 is a sectionalside elevation of the same. Fig. 8 is an inverted plan view of the same.Fig. 4 is an inverted perspective View of the improvement with the hairremoved and the cover partly open, and Fig. 5 is a perspective view ofthe Wedge-shaped block. V

The improved bow for stringed musical in struments is provided with theusual staff A, in one end of which is mounted to turn the screw-rod B,engaging a nut 0, held on the frog D, fitted to slide in the usualmanner on the end of the staff A. The frogD is preferably made of sheetmetal, but may be molded or made of other material, and is formed in itsunder side with a recess E, the front wall of which is formed byavertical extension F of the inclined bottom F, over which passes thehair G, as plainly illustrated in Fig. 2. The ends of the hair are tiedat G in the usual manner and extend over the inclined bottom F and theextension F, to be pressed securely in contact with the latter by awedgeshaped bloc}: H, fitting into'the recess E. The rear end of thewedge-shaped block II abuts against the wall I, formed as an extensionof the rear bottom part I, as is plainly shown in Fig. 2. The under sideof the frogD is adapted to be closed by a cover J, fitted to slidelongitudinally in suitable bearings K, formed on the sides of the frogD, as plainly shown in Fig. i. The top of the cover J extends over theunder side of the block H and the under side of that part of the hairpassing under the bottom F, so that the several parts are held in place,as shown in Fig. 2. In order to place and lock the hair in place on thefrog, the coverJ is removed, the opening E being opened by having theblock H removed. The tied end of the hair is then placed in the recess Eso as to rest against the extension F and the under side of the bottomF. The operator now inserts the wedge-shaped block H in the said recess,so that one end of the said block rests against the wall I of the recessE and the opposite beveled end of the said block presses against thatpart of the hair resting on the extension F. The wall I isslightlyinclined, as shown, so that the wedge-shaped block 11 securelypresses and locks the ends of the hair in place. hen this has beenaccomplished, the operator slides the cover J over the lower end of thefrog in the bearings K, so that the block II is held in place and theseveral parts are locked together.

.It will be seen that a frog constructed in this manner permits ofreadily inserting the ends of the hair in rehairing the bow.

Having thus fully described ourinvention, we claim as new and desire tosecure by Letters Patent- 1. In a bow for stringed musical instruments,the combination, with a frog havinga recess adapted to receive the endsof the hair, of a wedge-shaped block fitting into the said recess andadapted to press and lock the hair in place on one of the Walls of thesaid recess, substantially as shown and described.

2. In a bow for stringed musical instruments, the combination, with afrog formed with a recess and having part of its bottom inclined andformed with an extension, being one of the walls of the said recess, theother part of the bottom being also provided with an extension formingthe opposite wallof the recess, of a wedge-shaped block adapted toengage the said recess and resting with one end against one of the wallsand pressing with its opposite end the hair in contact with theextension of the inclined bottom part, substantially as shown anddescribed.

3. In a bow for stringed musical instrnments, the combination, with afrog formed with a recess and having part of its bottom inclined andformed with an extension, being one of the walls of the said recess, theother
